Question 1
1 / -0

Formaldehyde is not used in the manufacturing of

A
bakelite

B
nylon-6

C
urea resin

D
melamine resin

Solution

Formaldehyde is not used as a monomer in the manufacture of nylon-6 as caprolactum is a monomer for the synthesis of nylon-6.
Question 2
1 / -0

Polymerization in which two or more chemically different monomers take part is called

A
addition polymerization

B
copolymerization

C
chain polymerization

D
homopolymerisation

Solution

Polymerization in which two or more chemically different monomers take part is called copolymerization.
Question 3
1 / -0

Which of the following statements is not true?

A
Synthetic rubbers are co-polymers of 1, 3-butadiene or its derivatives with another unsaturated monomer.

B
Natural rubber is considered as a linear polymer of 2-methyl-1, 3-butadiene.

C
Vulcanisation is the formation of sulphur bridge between different chains of rubber.

D
Natural rubber has the trans-configuration at every double bond.

Solution

Natural rubber has the cis-configuration at every double bond.
Question 4
1 / -0

Which of the following polymers can be vulcanized?

A
Thiokol

B
Orlon

C
Neoprene

D
Polyisobutylene

Solution

Only neoprene contains allylic double bonds which help in introducing sulphur bridge between different polymer chains.

1 / -0

Which of the following can be used as a monomer in a polymerisation reaction?

A
CH₃CH₂Cl

B
CH₃CH₂OH

C
C₆H₆

D
C₃H₆

Solution

Only olefins (here C₃H₆) and dienes undergo addition polymerisation.

1 / -0

The fibre used for the manufacture of chords and carpets is

A
polyethylene

B
polypropylene

C
polyacrylonitrile

D
polyvinyl chloride

Solution

The fibre used for the manufacture of chords and carpets is polypropylene.

1 / -0

The polymer used as cement to allow electric bulbs to hold their metal holders is

A
glyptal

B
novolac

C
polypropene

D
polyurethane

Solution

The polymer used as cement to allow electric bulbs to hold their metal holders is novolac.
